After one dog died and two were sent to the wrong destinations on flights in March, United Airlines temporarily banned pets in order to reevaluate its policy. Yesterday, the carrier announced that while it will be allowing pets back on board, several new restrictions will go into place—including regulations around size, breed, and species, and where you and your pet are traveling to and from. The policy was made after consultation with American Humane, who will be collaborating with United on pet travel going forward.

Starting June 18, 2018, several dog and cat breeds will be banned from traveling in United's PetSafe program—in other words, cargo. According to the site, the ban applies to brachycephalic (short-nosed) dogs, such as pugs and shih-tzus, and strong-jawed breeds, due to their higher health risks—in total, 21 different dog breeds and four cat breeds were mentioned, and you can check out the full list here. In addition, only cats and dogs will be permitted in PetSafe—no other animals will be accepted. As the Los Angeles Timespoints out, it's unclear how service animals and emotional support animals factor in to this policy, which has been a contested issue across several airlines. Small pets will still be allowed in the cabin (including some of the breeds banned in PetSafe), so long as they fit under your seat—not in the overhead bin.

United also stipulated that pets will not be allowed in cargo when you're traveling to and from Las Vegas, Palm Springs, Phoenix, and Tucson between May and September, due to the excessive heat. Among other PetSafe restrictions: Reservations must be made at least five days in advance; most international destinations fall under PetSafe, with the exception of India and Australia; the number of connecting flights your pet can travel on will be limited; crates can't be taller than 30 inches; and you must provide documentation prior to your reservation. Although this may seem like a laundry list of rules and regulations, in the long run, it might be worth it—it's about time airlines started taking our furry friends' safety seriously.
